Ask the Wizard (@codspeedbot) right from GitHub

When a benchmark regresses, the investigation usually starts in a pull request comment, and that's exactly where it should end too. Mention @codspeedbot in any pull request comment, issue comment, or review comment and the Wizard will analyze your performance data, explain what happened, and propose a fix directly in GitHub.
